If you search the internet with the question, “Is it okay to use
cannabis products while taking
prednisone?” , you will find positive (though cautionary)
responses.
Just as with pharmasuticals.

For great sleep and some pain relief I prefer small doses of
THC/CBD to anxiety, depression, and other drugs.

I do take them at bedtime and
prednisone in the early morning to lessen any interaction (I hope).

At 88, in assisted living, with
PMR since 2016, I reckon if it works use it.
I do keep my doctor aware of my proactivity on health and quality of life issues 🙏😇🌹
